Single work

820-2530 No start.


Have my green light on the magsafe.
Have stable ppbus_g3h.
Have pp3v3_s5 but the board does not power on when we short the smc_onoff pad to ground.
No start in SMC bypass neither.
After a thorough ultrasonic cleaning bath the board turns on, chimes and has video but it doesn’t have back light.
Checked the inner area of J9000, LVDS connector, and it had some minor corrosion. Replaced it with a new one and the board now has a nice backlight.
Passed ASD…ready to go!
